I'm seeing this as a glimpse of an alternate Erfworld, where Wanda formed her own Side instead of sticking with Stanley, and popped this intimidating Warlady while having Sylvia as her consort, resulting in a Signamantic blend of the two scary ladies.

The Arkentool doesn't attune to death magic, because dark mirror Wanda never had the same experiences... something, instead- of rage and fire. Something suitably broken like full control of all fire based/attack units within a certain range (we just build a few siege towers and rams, and the idiot archers light up every time. Instant turn.) or the capacity to take any spell directed in her area and redirect it as a fire spell outwards - or provides juice for her own fire spells.
